Reason for purchase:
Improve the ventilation of silver skin

Reviews:
Originally, the silver skin ventilation system used in the roaster was unstable, which made it more difficult to bake beans. We entrusted Hongdao Food Baking Machinery Co., Ltd. to improve the ventilation problem. After replacing the mechanical damper of the HD roaster version, the ventilation effect changed. It is quite stable, and the hand feel is quite strong when switching the number of stages, and the roasting beans can be adjusted more easily.
